MacBook Air. And I won't. That doesn't stop me from looking at the most recent ultrathin laptop competition to see where Apple might be able to improve the design that turns two years old in January., I said I wouldn't hazard any guesses on what Apple may do with the
Enclosure: This will be a tough act to follow. The original design was good enough that Apple didn't change it for gen 2--aka Rev. B--of the Air. And the aluminum enclosure was a trendsetter, which all MacBook Pros (and other PC makers) eventually copied.
But that doesn't mean the Air is perfect. The razor-thin slab of aluminum provides little room for ports and connectors. (Apple's implementation is a flip-out set of USB, Mini DisplayPort, audio ports that retract back into the body.)
A design modification that the Dell Adamo uses (some say retrogressed to) was putting the ports on the back (behind the screen). This allows Dell to offer a fuller array of connectors.
Hewlett-Packard, for its part, went another route: it just made itsslightly thicker (at 0.8 inches) than the Air, allowing a couple more connectors (a second USB port and an SD card slot). HP also molded the base of the Envy in magnesium, which makes it lighter, according to HP.
Then there's just-announced. This is even thinner than the MacBook Air and puts the CPU-complex-plus-circuit-board (aka motherboard) behind the screen, not underneath the keyboard--standard design practice for all laptops.
Of course, there's the recurring rumor that Apple is looking at different materials to make it even lighter while maintaining its famous sturdiness. This could potentially be a combination of aluminum and something like carbon fiber. (Though, as stated above, HP claims that magnesium is the way to go.)
Other possibilities: make one model bigger (wider), a la the Dell Latitude Z, which offers a 16-inch 1600x900 WLED Display and at its thickest point is only 0.79 inches.
Or make it smaller. Theis a great example of how light (1.6 pounds) and thin (0.55 inches) a premium laptop (technically it's a Netbook) can be.
There is the remote possibility that a version of the Air becomes a tablet. And that would mean potentially a new enclosure and new silicon.
Graphics:. The second feature I'll touch on is graphics. A good graphics chip is tough to squeeze into ultrathin designs and this a major feature that set the Air apart from other slim designs, which use the Intel Graphics Media Accelerator 4500MHD.
Apple, with the Rev. B of the Air, introduced Nvidia 9400M (aka, Ion) graphics silicon. This delivered decent performance and actually made the Air run cooler (I know, I've used both the original Air and Rev. B extensively.)
Let's be clear--the graphics on the original Air was poor. And the source of many gripes about the original design (which proves how important the graphics chip is now). Apple chose to go with Intel's X3100 graphics (they didn't have much a choice in 2007, when design decisions were made), which superheated the bottom of the unit when watching video. My Air would get so hot that I would have to place a large, flat picture book (in effect, a crude heat sink), between my lap and the MacBook Air.
So, what's next after the Nvidia graphics in Rev. B of the Air? There's Nvidia's upcoming Ion 2 graphics, which is still a mystery. I even queried an Nvidia executive about this recently in an interview, but mum's the word. I have confidence that Nvidia will deliver a solid solution that offers an optimal balance between power efficiency and performance.
Nvidia also offers the GeForce G 105M, which is used, for example, in the HP dm3t consumer ultrathin laptop.
Then there's the ATI Mobility Radeon HD 4330 graphics chip, which Advanced Micro Devices describes as a "thin and light mobile graphics processor...delivering unprecedented performance-per-watt...while watching Blu-ray movies." (The Blu-ray aspect may be overkill for an ultrathin, especially in the case of the Apple, which does not offer Blu-ray drives in its MacBook line.)
This ATI chip.
I won't dive into processors here. Suffice to say that Intel continues to expand its variety of low-voltage (e.g., SL9600) and ultra-low-voltage processors (SU9600). Maybe more enticingly, Intel will bring out low-power versions of the Core i series of mobile processors next year. Probably sooner rather than later. This is likely what Apple is targeting for any major revamp of the Air.
